Question

我写了一个php代码来生成包含mysql表中标记的xml文件。但是我收到了这个错误信息：

XML解析错误：XML或文本声明不在实体的开头地点：http://localhost/onlinetaxi/phpsqlsearch_genxml.php 第5行，第1列： ^

我在谷歌搜索它，答案说它是由白色空间引起的，我应该删除它。它删除了每个空白区域，但问题仍然存在有人可以帮助我吗？

<?php  
require("phpsqlsearch_dbinfo.php");
// Get parameters from URL
//$center_lat = $_GET["lat"];
//$center_lng = $_GET["lng"];

// Start XML file, create parent node
  $dom = new DOMDocument("1.0");
   $node = $dom->createElement("markers");
 $parnode = $dom->appendChild($node);

 $connection=mysql_connect ("localhost","root");

 // Iterate through the rows, adding XML nodes for each
 while ($row = @mysql_fetch_assoc($result)){
